I have a Jandy Lite 2 heater that is about 8 years old. I am getting this fault on it. I checked the two fuses and one of them was blown so I replaced it and the heater worked fine for a day. A day later the problem came back with another blown fuse. I replaced that as well but now it doesn't light at all.
I removed the hot surface igniter and it appears to be broken as it should look like this:
But mine looks like this:
Could that have caused the problem(s) with the blown fuse?
I have ordered a new igniter from Amazon so I will replace it when it arrives.
Is there any reason why there are two fuses - one is inline with either wire. Shouldn't one fuse do the trick? And does the polarity of the wires matter, and/or does it matter if I switch the ends of the inline fuse holders? In other words there are two fuses with the same black holder. Let's say that the wires connecting Fuse 1 are wires A and B and the wires connecting Fuse 2 are wires C and D. Would it matter if I somehow switched them and connected wire A to C instead of B?
